Can the Same Term Have Different Meanings in Different Fields?

Can a Familiar Academic Term Change Meaning When You Cross Disciplines?

Yes, and the most troublesome cases are often not obviously technical words. Terms such as hypothesis, significance, validation, replication, engagement, or performance can look perfectly familiar while carrying disciplinary assumptions that are not familiar at all.

This creates a subtle problem in interdisciplinary research. When you encounter an unknown term, you know to investigate it. When you encounter a familiar one, you may import your own discipline's meaning without realizing that anything needs checking.

The question is therefore not merely whether disciplines have different jargon. It is how you recognize when shared vocabulary is hiding different meanings.

Shared Vocabulary Does Not Guarantee Shared Meaning

The Dangerous Terms Are Often the Ones You Think You Already Understand

Disciplines develop specialized meanings through use

Scientific and scholarly vocabulary develops inside disciplinary communities. Researchers are trained not only in facts and methods but also in ways of using concepts and technical language. A word that appears ordinary outside a field can therefore acquire a narrower, broader, or otherwise specialized meaning within it.

Research on cross-disciplinary communication has documented this directly. Donovan, O'Rourke, and Looney examined how researchers in cross-disciplinary groups understood the term hypothesis and found substantial variation in perceptions of what hypotheses are, what role they play in science, and how they are used. Some of those differences reflected disciplinary training.

The problem is broader than any one term. Specialized vocabularies can vary because disciplines organize and categorize knowledge from different perspectives. Research on terminological variation has likewise shown that disciplinary background can influence how specialists name and conceptualize phenomena.

There are several ways the same term can differ

When two disciplines use the same word, the difference is not always a completely different dictionary definition. Semantic variation can occur at several levels.

A difference in one of these areas does not automatically mean the disciplines are discussing completely different concepts. It tells you that equivalence needs to be examined rather than assumed.

Even basic research terminology can vary

Words associated with research itself can produce disciplinary misunderstandings. Donovan and colleagues note potential variation around terms including hypothesis, empirical, qualitative, quantitative, experimental, replication, and validation. Their study of hypothesis illustrates how researchers can use apparently shared scientific vocabulary while holding different assumptions about what the term entails.

This matters because methodological words can affect more than communication. If collaborators believe they agree on what counts as validation, replication, or evidence when they actually mean different things, those differences may eventually affect research design and interpretation.

Context usually reveals more than the isolated term

Do not investigate disciplinary meaning by comparing dictionary definitions alone. Read the sentences and arguments surrounding the term.

Ask what authors treat as examples and non-examples. Look for explicit definitions, but also examine what variables surround the concept, what researchers measure, which theories they cite, and what conclusions they draw from it.

A particularly useful question is: What would count as evidence of this concept in this discipline? The answer often exposes assumptions that the label itself conceals.

Operationalization can expose hidden differences

Suppose two literatures repeatedly use the same term. One measures it through participant self-reports, while another identifies it through observed behavior. That alone does not establish that the concepts differ, because the same construct can sometimes be measured in several ways.

It does, however, give you a reason to inspect the construct more closely. Compare what each measure contains, how authors interpret the resulting scores or categories, and what theoretical definition justifies the operationalization.

This moves the analysis beyond word matching toward the broader question of whether the concepts themselves are sufficiently equivalent across disciplines.

The same spelling can also distort your literature search

Semantic variation affects retrieval as well as interpretation. If you search a term across multidisciplinary databases, records may contain that word for several disciplinary meanings.

The result can be deceptively impressive: thousands of apparently relevant records, many of which address a different concept.

Inspect terminology around each disciplinary use. Additional terms, subject headings, theories, population terms, or contextual concepts may help distinguish one meaning from another. Developing a working vocabulary for the unfamiliar field can therefore improve both conceptual understanding and search precision.

Meaning can vary within a discipline too

Do not replace one simplification with another. "Psychology means X, while education means Y" may be too neat. Disciplines contain subfields, theoretical traditions, methodological communities, and historical changes in terminology.

A term may be contested within one field or may have shifted meaning over time. Before describing a meaning as disciplinary, check whether several independent sources support that characterization and whether important competing definitions exist.

Historical movement can change a term's meaning

Terms travel. A concept may originate in one discipline and later be imported into another, where researchers modify it to fit different questions or theoretical assumptions.

Tracing the earlier literature behind a concept can reveal whether two disciplines inherited the same original idea and subsequently changed it, or whether they independently arrived at similar terminology.

That history can explain why two contemporary literatures seem to speak the same language while meaning somewhat different things.

Sometimes you need a local working definition

In interdisciplinary research, eliminating every terminological difference may be impossible and unnecessary. What matters is preventing hidden disagreement.

If a term is central to your study, define how you will use it and identify where that use aligns with or departs from the disciplinary literatures involved. In collaborative research, discussing those definitions explicitly can help establish common ground. Donovan and colleagues argue that making terminological and conceptual assumptions visible can improve cross-disciplinary understanding precisely because researchers may otherwise assume that familiar terms are univocal.

Common Mistakes With Shared Terminology

Treat Familiar Cross-Disciplinary Terms as Questions, Not Answers

You do not need to investigate every shared word in every paper. Prioritize terms that affect your search strategy, theoretical framework, inclusion criteria, measurement decisions, or conclusions.

The aim is not terminological tidiness. It is to prevent a shared word from creating a false impression that the underlying literatures are already conceptually aligned.
